Hybrid Technology Enters the Real World

In this article the authors discuss the energy savings associated with new hybrid technologies currently being implemented in Japan that provide diesel multiple unit (DMU) trains with a prototype hybrid battery-diesel system that boasts up to 20 percent savings in fuel costs. The batteries used, lithium-ion (Li-ion), will also allow the train to cut particulates by up to 60 percent. The battery consists of 48 1 kWh modules which weigh about 30 kg each. The one-ton array, being as large as it is, is put in custom designed racks in a coach adjacent to the main power car. The article also describes some of the interest this technology is gathering in Europe, as it offers a number of improvements to similar systems that are found in Britain's Channel Tunnel Rail Link, for example.
